N2  - In this work, the design of reflectarray surface currents able to meet both radiation and  arbitrary  geometry constraints  is  dealt  with.  Towards  this  goal,  the  synthesis problem  is  formulated  as  an  inverse  source one,  and  a  closed?form  expression solution is derived to compute the non?radiating current components able to modify the  geometry  of  the  reflective  surface  without altering  the  desired  radiation features.  Some representative  numerical  benchmarks  are  shown  to assess  the proposed  synthesis  methodology,  as  well  as to  verify  its  flexibility  in  realizing "forbidden?regions" of arbitrary shape.
